IMPROVEMENT IN PENS.

Specification forming part of Letters Patent No. 116,242, dated J nne20,1871.

N atnre and Objects of the Invention.

Description of the Accompanying Drawing.

Figure 1 is a perspective drawing of afountain-pen embodying myinvention. Fig. 2 is an enlarged perspective view of the pen with thehandle and exterior adjusting-band removed. Fig. 3 is a cross-section ofFig. 2. Fig. 4 is a perspective view of the exterior adjusting-band.Fig. 5 is a section from point to rear of the adjusting-band. 7

General Description.

A is the handle of the pen, and B the pen. The latter is composed ofthree jaws or nibs, b, and a socket, I), for the reception of the handleA. Below the socket the jaws 1) form, to-

gether, a triangle in cross-section, and each jaw is tapering in form,as shown, so as to admit of their uniting in a common point, X. The inkis contained between the jaws b, the sides of the jaws beingsufficiently close together to prevent the escape of ink.

For the purpose of cleaning, these jaws may be bent back or sprung toadmit of the introduction inside the jaws of a brush or cloth.

a In order to keep the jaws together while in use, and furnish a meansfor the adjustment of the pen to write different thicknesses of strokesor lines, I provide the exterior band 0, which isso shaped as to fit theexterior of the jaws, and adapted to slide up and down the jaws totemper or adjust the flexibility of the nibs or points of the pen. Atapering cup, 0, is attached to the band 0, the sides of which serve tohug the jaws of the pen to prevent spreading, and the concavity of whichforms a chamber for the occupancy of ink, to increase the capacity ofthe pen for ink, and thus enable it to write a Very long time withoutrefilling.

This pen is peculiarly adapted, in addition to its use withwriting-fluids, to receive for use Writing-paste, which, when wet bydipping in water, will feed acolored fluid to the pen-points forwriting.

Owing to the peculiar construction of this pen it is calculated to writepencil-like, with anequal thickness of line for the up-and-down strokes,and perform its work with less fatigue to the penman than the ordinarywriting-pen.

It can, however, be adjusted to write with heavy and light strokes, toadapt it for bold penmanship.

Claim.

A fountain-pen, constructed with taper elastic jaws or nibs, b b b, andexterior sliding ring or band C, substantially as and for the purposespecified.

In testimony of which invention I hereunto set my hand.
